Liverpool hero Phil Thompson says the lack of a settled back four continues to work against Manchester United.

United's defensive woes this season have left them 16 points off league leaders Liverpool from as many games, and they visit Anfield on Sunday.

Thompson told Sky Sports: "Me being a defender will look at that and wonder why and how and where - I think it's the number of players he has used in a back three, a back three or a back five.

"The chopping and changing, players getting injured, Jones who seems to come in and go out because he gets injured, there's so many permutations."

He added: "They'd bite your hand off for a draw at Anfield, and Jose likes nothing better than frustrating, biding his time and if they can, take the game to the opposition with set-pieces and pace."
